Specification of Letters Patent.

Patented Sept. 12, 1911.

Application filed February 4, 1910. Serial No. 542,060.

T all whom it may concern:

Be it known that I, EDWARD N. HALLETT, a citizen of the United States,and a resident of Canton, in the county of Bradford and State ofPennsylvania, have invented a new and Improved Dumb-\Vaiter, of whichthe following is a full, clear, and exact descript-ion.

My invention relates to dumb-waiters, and it has for its object toprovide a pantry closet on a dumb-waiter so that when food is placed 011the shelves of the closet the dumbwaiter may be lowered through anopening in the floor of the kitchen to the cool air of the cellar.

Another object of the invention is to construct a supporting frame onthe dumb' waiter so that when the dumb-waiter is lowered with the frame,the working parts are disposed below the floor of the kitchen.

Another object of the invention is to provide a movable frame with whichthe closet is connected, the closet having a limited movement relativelyto the frame, and the frame having a limited movement relatively to thestandards, there being springs adapted for cushioning the closet againstthe frame at the termination of its movement in one direction relativelyto the standards.

Still other objects of the invention will appear in the followingcomplete description.

In this specification I will describe the preferred form of myinvention, it being understood that the scope of the invention isdefined in the appended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a front elevation of my invention with the closet raisedthrough an opening in the floor of a kitchen; Fig. 2 is an enlargedview, similar to that shown in Fig. 1, with the closet lowered below thefloor of the kitchen; Fig. 3 is a vertical sectional view of the samewith the closet lowered and the valves of the closet and the ice chamberopen to afford communication; Fig. 4 is a view similar to that shown inFig. 3, but with the closet slightly raised a distance, the valves beingclosed; and Fig. 5 is an enlarged plan view showing the floor of thekitchen cut away.

By referring to the drawings it will be seen that standards areprovided, which are connected at their lower terminals by a rod 11, thestandards 10 being connected to an open frame 12 at their upperterminals. The auxiliary standards 13 are disposed one at the outer sideof each of the standards 10, these auxiliary standards being connectedat their upper terminals with the open frame 12 by frame members 14,there being connecting frame members 15 at the lower terminals of theauxiliary standards 13, which connect the auxiliary standards 18 withcoupling members 16 by which the standards 10 are connected to the rod11. The standards 10 and 13 are hollow, and in them are disposed legs 17and 18, these legs 17 and 18 being held in their proper positionsrelatively to the standards and auxiliary standards by set screws 19.The legs 18 have horizontal feet 20, which project at each side beyondthe legs 18, these feet 20 being connected to sleeves 21 in which theauxiliary standards are disposed respectively by means of obliquelydisposed rods-22.

A closet 23 is disposed between the standards 10, this closet havingbrackets 24, one projecting fro-m each side, the brackets 24 having eachtwo openings therein in which are disposed respectively standards 10 andbars 25. The bars 25 are connected at their bottom by a rod 26, and theyalso have lateral projections 27 with openings therethrough in which aredisposed the standards 10, coil springs 28 being wound around each ofthe standards 10 between the bracket- 24 and the extensions 27.

To the sides of the closet 23 are secured loops or rings 29 in which thebars 25 are disposed, these bars 25 having stops or enlargements 30 attheir upper terminals to prevent the loops or rings 29 from slipping offthe top of the said bars.

Secured to the standards 10 at some distance from their lower terminalsare studs 81, which are adapted to engage the springs 28, the brackets24; having indentures at the side of the openings in which the standards10 are disposed to permit the brackets to pass above the studs 31, thestuds being adapted to engage the upper terminals of the springs 28 whenthe brackets are moved to the top of the standards 10.

Secured to the frame members 14: are

brackets 32 in which are jou'rnaled pulleys 33, there beingcounterweights 34 which have brackets 35 in which pulleys 36 arejournaled. are secured to the brackets 32 and are disposed around thepulleys 33 and 36 respectively, and thence downwardly where they aresecured to the brackets 24 at their lower terminals 38.

- The floor of the kitchen is represented by the numeral 39,this floorhaving an opening 40 therein, through which the closet 23 i'sadap'tedtube moved, a hatch 41 being provided to cover this opening 40 in thetloor,-thishatch 41 being connected to the top of the closet 23 bysupports 42 so that when the closet 23 is raised the hatch 41 is movedupwardly therewith, and when the closet 231is lowered the hatch 41 isbrought down around the opening 40 in the floor 39 closingit. The openframe 12 is secured to the under side of the floor 38 by means of clamps43."

Secured to the under side of the floor 39 in the rear of the opening 40there is a bearing 44 in which is journaled a rock shaft 45, two arms 46and 47 being secured to this ro'ck'shaft. To the arm 46 is pivoted astud 48, which projects through a smaller opening in the floor 39. Abolt 49 is dis posed in guides50, the bolt 49 having a pin disposed in aslot 51 in the arm 47, the arm 47 being connected to the lower end ofthe guide by means of a spring 52. The bolt 49 has a head 53, which isadapted to engage the top of a cleat 54 secured to the closet 23 toprevent the upward movement of the closet.

On the frame members 55 is mounted means for supporting an ice chamber64, which is provided with a valve seat 67, there being a second valveseat in the outer terminal of the collar 73, valves 69' and 7 6 beingprovided for closing these valve seats, the valve 76 being connectedwith the sleeve 74, The closet is provided with valve seats 68 and 83,which are adapted to be closed by valves and 84. When the closet islowered the arms open the valves 69 and b 70 nd the plate 82 engages thearm 81, to

rock the shaft 77, to which the arm 78, which is articulated to thesleeve 74, is secured, thereby moving the sleeve 74 outwardly so thatthe member 76 will contact with and open the valve 84, the valve 7 6being moved through the closet.

In using my inventiomthe operator by pressing'on the stud 48 removes thehead 53 of the bolt 49 'froin the cleat 54, and as this is done thesprings28 open to raise the closet slightly, the counterweightscontinuing this movement so that with very little help the Cables 37 areprovided which operator may raise the closet through the opening 40through the floor 39 of the kitchen. As the closet moves upwardly therings 29 engage the heads 30 of the bars 25, thereby carrying the bars25 with them. The indentures 87 in the sides of the opening in thebrackets 24 through which the standards 10 are disposed permit thebrackets to move above the studs 31, the studs 31, however, engaging theupper terjminals of the springs 28 to prevent the springs from passingthereabove. As the closet continues to move upwardly it assumes theposition shown in Fig. 1 of the drawings, in which the brackets 24 aredisposed just below the plane of the floor 39, the closet 23 beingdisposed above the floor, the bars 25 being disposed through the openingin the floor to serve as lateral supports for the closet 23 in itsraised position, the springs 28 serving to cushion the termination ofthe upward movement of the bar 25 inasmuch as the projections 27 engagethe lower terminals of the springs 28, the upper terminals engaging thestuds 31. \Vhen the operator has finished using the closet it may bepushed downwardly without difficulty, inasmuch as the counter weights 34provide a very even balance, there being no necessity of carrying anyice or heavy bodies in the closet. As the closet 23 is pushed downwardlythe brackets 24 again engage the upper terminals of the springs 28, thelower terminals of these springs engaging the projections 27 and forcingthe bars 25 downwardly, the closet assuming the position shown in Fig. 2of the drawings when it is disposed below the floor 39, the hatch 41moving down with the closet 23 to cover the opening 40 in the floor.
